PokeBonk Butterfree
Pokemon · Caterpie line · last checked 2026-10-20
PokeBonk Butterfree is a Bug and Flying Pokemon that you cannot pick at the start of a run: it is the evolved form of Caterpie, a League Pokemon. Play Metapod and it evolves into Butterfree automatically at player level 36, which raises your HP and damage multiplier to 1.24x. Butterfree keeps the Caterpie kit and upgrades the Ultimate to Scale Storm. The line sits in B tier with a Kit Score of 36.4.

How to get Butterfree in PokeBonk
You do not unlock Butterfree directly. First unlock Caterpie through its League challenge and catch it; the PokeBonk unlock Pokemon guide lists the conditions. Then pick Caterpie for a run and level up: evolution in a run depends only on your player level, not on stones or trades, so Butterfree arrives at level 36.
Each stage adds 0.12 to your HP and damage multiplier, so an evolved form hits harder and takes more hits than the Pokemon you started with. An Eviolite helps until the last stage. See PokeBonk evolution for every line.
Butterfree moves and passive
Butterfree uses the same four-move kit as Caterpie; evolving does not swap moves. Its passive is Metamorphosis: +15% experience and +20 shield. Evolves soon (Metapod at Lv. 8, Butterfree at Lv. 36). As Metapod, the cocoon gives you +30 armor.

| 2 | Bug Bite | Bug | Physical | Strike | Level 2 |
| 3 | Gust | Flying | Special | Vortex | Level 4 |

Butterfree Ultimate
At this stage the Ultimate is Scale Storm, lasting 3.2 seconds: A cloud of butterflies and colorful scales puts to sleep, paralyzes and poisons over a huge area and ends in a gale. The PokeBonk Ultimate guide explains how to charge it faster.
Butterfree evolution levels in PokeBonk
In PokeBonk every evolution happens by player level inside a run, whatever the main games ask for. The Caterpie line evolves like this: Caterpie evolves into Metapod at level 16 and Metapod evolves into Butterfree at level 36.
Butterfree stats in runs
The game turns base stats into run stats with the share of each stat in the base stat total, so a balanced Pokemon and a lopsided one end up with different strengths. Each evolution stage adds 0.12 to the HP and damage multiplier. These are the starting values before Lab upgrades, items and vitamins:
| Form | Stage | Max HP | Armor | Speed | Physical | Special | Damage |
|---|---|---|---|---|---|---|---|
| Caterpie | 0 | 132 | 8.3 | 1.09x | 1x | 0.94x | 1x |
| Metapod | 1 | 152 | 11.9 | 1.03x | 0.94x | 0.97x | 1.12x |
| Butterfree | 2 | 138 | 8.2 | 1.05x | 0.96x | 1.09x | 1.24x |

Where Butterfree appears as a boss
Besides being playable, Butterfree is listed as a boss on the maps: Viridian Forest as a possible zone 1 Summoner. Boss HP is budgeted from your own damage per second, so the fight length stays close to the game's targets; the PokeBonk maps page lists every boss slot.
