I like how Mr. Satan worked in UB22. (well, other than the utter impossibility of using his Champion Dance in real combat). Stuff like that should be applied to Sparking! More explosions=happy Atari board fans, and more useful Mr. Satan = happy me... We all win! Except for you guys.

. Umm... I jest...

But yeah, applying UB22 Satan style to the Sparking version could turn out awesome. Though note that having him throw rocks actually says more for his strength... with a gun, it doesn't matter how powerful you are... the projectile is always the same strength (I guess you could be thrusting your fist out while firing to increase the bullet's velocity?

), but with a rock, the force of the ensuing collision is dependent on how hard the rock is thrown... so if you can throw a rock and do more damage than with a gun, go for the rock!
But if this is not the case... a gun would be the better choice. ... I guess that was a wasted sentence. Though... are there any characters with guns in the game? It'd be interesting to see how they play (And it'd just be awesome to watch Raditz deflect bullets... that smarts...)
(Oooh... random addition: you think Mr. Satan would be influential enough to call out some aircraft or super explosive to make a big explosion? Actulaly that seems more in the style of the red ribbon army.. .. Something's eating my letters again.)
