Ooh I've wanted to write out a comparison in terms of tf2 classes!
Squid- Probably FaN Scout. Good mobility for capping points, focus on disabling, only attacks from flank.
Goldfish- Soldier. Very good mobility, versatile in almost any role. Works by disabling people (goldfish disables, soldier blasts people to make their movement predictable)
Pyra- Pyro. Reasonably fast, devastating when catching someone unaware, can control other people's positioning (pyra ram/pyro airblast). Helpless at mid-long range, hard to disable (disabling people in tf2 works by blasting them up with a pill or rocket, which pyro can reflect).
Junker- Heavy. Slow but good maneuverability and close-mid firepower.
Galleon- Demo. Slow and kind of defenseless at close range vs scouts, but very good defense and tons of damage otherwise.
Spire- Sniper. Good damage at most ranges (if you can hit), vulnerable, bad mobility.
Mobula-
