Totenkopf

I remember now about Ataru form: just is best for one on one fights up close. Sucks against multiple opponents...unless you time it right... Maginally less miserable at blaster deflection than Makashi, but I would say ideal vs melee. Or jedi/sith weilding lightsabers. Gives extra oomf to power strikes. While not as powered up as Juyo (which is essentially similar) it gives a boost to your attack & damage power. Defense is good against single opponent you are focused on. In fact I'd use this against Colonel Tobin.

Shien...like soresu but many opponents instead of single. However your current target you will be weak agianst. Funny though: while not as good as duelist forms, it is better vs lightsabers than some. More Blasters & some lightsabers--the best time for that is in a few spots in the Trayus core.
