^ couldn't edit the post so I deleted it to clean it up a bit. Was posted late and had some errors.
Tried a couple times with Shiba. He is fast and is melee is powerful. It might have a little invincibility even.
Special shot causes a lot of stun, especially effective in close groups of enemies.
His super has the least invincibility, but also the most time to move freely after calling it. It also homes in until it finds a target which is nice in case they all go to a weak enemy. --- Riskbreaker.
