Best Starter Units in Undertale Adventures X
Picking the Undertale Adventures best starter setup is less about chasing rare units and more about building a balanced roster that can survive early waves. In Undertale Adventures X — the Roblox Undertale-inspired tower defense adventure — new players should combine dependable early damage with at least one support option, rather than stacking a single damage type.
Judge your starter units by how reliably they clear the first waves, not by rarity. Frisk and Papyrus carry most accounts through the early game until stronger summons arrive.
| Unit | Role | Early-Game Value | Best Use |
|---|---|---|---|
| Frisk | Starter progression unit | ★★★★☆ | Learning placement, first story stages |
| Papyrus | Early/mid-game damage | ★★★★☆ | Stable opening formations |
| Flowey | Flexible filler | ★★★☆☆ | Testing layouts, filling roster gaps |
| Toriel | Defensive support | ★★★☆☆ | Stabilizing sustained waves |
| Undyne | Sustained core damage | ★★★★★ | Long-run carry once obtained |
| Sans | Advanced damage and control | ★★★★★ | Late-game and boss stages |
Frisk: The Safe Pick
- Easy to understand in a basic team setup
- Ideal for learning upgrade timing
- Move to a secondary role later
Papyrus: Reliable Damage
- Dependable coverage before premium units
- Pairs well with Frisk for broad coverage
- Keep upgraded until stronger options arrive
Toriel: Early Stability
- Supportive defensive utility
- Protects your main damage dealers
- Best in a complete team, not as a solo carry
Starter Progression: Step-by-Step
Follow this path from your first lobby visit to a stable early-game roster. Each step builds on the tower-defense loop of preparing a team, placing units along the enemy route, and spending earned resources on upgrades.
Prepare a Balanced Team in the Lobby
Open the unit or inventory menu, choose your available damage dealers and support options, and place Frisk and Papyrus in the active team. A balanced roster gives you room to recover from leaks during difficult waves.
Place Units at the First Choke Point
Watch the enemy route before spending all starting currency. Deploy near corners, bends, and shared paths where enemies stay in range longest, and keep enough currency for the next wave.
Upgrade Before Expanding
Improve your best-positioned unit before placing several weak units across the map. Concentrated upgrades are easier to manage early than a wide field of under-leveled units.
Clear Stages and Reinvest Rewards
Replay stages for currency and experience, upgrade units that consistently contribute across full waves, and test new units in normal content before difficult stages.
Transition to Core Carries
Once summons provide Undyne or Sans, shift Frisk into a secondary role and build around one or two main carries supported by Toriel-style utility.
A strong position can outperform a higher-cost unit placed where it sees very little of the route. Prioritize coverage over price when placing starters.
Summoning and Traits for New Accounts
New players often waste early resources by summoning as soon as currency arrives. A smarter plan: establish a functional roster, then reserve valuable currency for high-impact targets.
| Decision | Recommended Action | Why It Matters |
|---|---|---|
| Early summons | Fill missing roles first | Coverage gaps hurt more than duplicates |
| Routine spending | Set a minimum reserve | Keep currency for limited banners |
| Rarity evaluation | Compare role and upgrade potential | Rarity alone does not replace coverage |
| Duplicates | Keep until use is confirmed | May be needed for enhancement systems |
| Saving | Build reserve after team is functional | Prepares you for new unit releases |
Do not spend reroll resources until a unit is confirmed as part of your long-term team. Prioritize core damage dealers first, then essential supports. Rerolling temporary starter units wastes limited resources.
| Trait Focus | Best Unit Role | Resource Priority |
|---|---|---|
| Damage-focused traits | Main damage dealers | High for permanent carries |
| Range traits | Units needing coverage | Solves placement weaknesses |
| Attack-speed traits | Repeated-attack units | Improves lane pressure |
| Support/uptime traits | Utility and control units | Reroll after team is stable |
Game Modes: Where Starters Shine
Different modes serve different progression goals. Use this comparison to decide where your starter team should spend time.
| Mode | Objective | Starter Suitability |
|---|---|---|
| Story/progression stages | Advance and unlock content | Best for learning and testing |
| Resource stages | Farm currencies and materials | Use consistent, fast-clearing teams |
| Challenge content | Test specialized builds | Wait until roster is developed |
| Limited-time events | Earn exclusive rewards | Check event rules, adjust team |
Focus on story stages first, then shift to resource farming once your starter team clears content reliably. Challenge content rewards optimization your early roster usually cannot support yet.

FAQ
Q: What is the best starter unit in Undertale Adventures X?
Frisk is the safest starter for learning placement and upgrade timing, while Papyrus provides the most dependable early damage. Together they cover the opening stages until stronger summons like Undyne become available.
Q: Should I spend all my currency on early summons?
No. Build a functional roster first, then set a minimum reserve and spend above it only when a summon directly fills a role gap or a limited banner offers high-impact targets.
Q: When should I reroll traits?
Only after confirming a unit is part of your long-term team. Prioritize core damage dealers first, followed by essential supports, and skip rerolls on starter units you plan to replace.
Q: Do I need rare units to progress early?
No. Placement quality and upgrade timing matter more than rarity in the early game. A well-positioned Frisk or Papyrus can outperform a stronger unit placed where it barely sees the enemy route.
