Character concept suggestions

I support the idea of ​​instead of creating new Phobies bringing mechanics to existing ones, I’ve been thinking since Red and Blue Speedola were made to use together why not they have the possibility of merging to become a single, even stronger Phobie together? Then, when they fused, they would become Purple Speedola, returning 1 key to the player

Purple Speedola
Race: Mech
10 Keys
Health: 2700
Damage: 650
1 Range
3 Movement
Ability: (The same as Mr Tramples with 0 to unlock and 2 cooldown )
Purple use your extreme speed to dash through enemies in a distance of 4 tiles and deal damage to anyone in the path also setting fire along the way

Once Red and Blue merge Purple will have 1 action
If Red and Blue were damaged before the fusion, Purple will also be damaged but will regenerate based on 30% of the health lost.
To fuse Red and Blue they need to be close to each other with at least 1 action, without the risk of the player accidentally fusing them.
