this video of all of Shockwave's appearances in the original cartoon. I've taken note of feats and abilties from him, obviously, but also some other characters.
Shockwave
• Stronger than Bumblebee - has knocked him down both by blasting him and just standing still and having Bee run into him
• Knocked down Brawn in one shot, though he got back up pretty quickly
• Weaker than Starscream, but is able to knock him down with a sneak attack
• Wields a handheld blaster, his hand cannon can vaporizing structures and robots as big as he is, and he has a built-in spotlight in his chest
• Commands the Sentinel Guards, who're individually weak but also numerous enough to overwhelm the Dinobots and force Bruticus into fighting strategically
• Knocked down by Swoop, but noticeably damaged him with one shot
• Stronger than Chromia
• Commands a network of cameras that let him see all of Cybertro
• Downed by shots from Powerglide, Ironhide and Inferno
• Seems to be noticeably stronger in cannon mode, knocking down an entire group of Autobots and even injuring Bruticus
• Battled and critically injured Omega Supreme, albeit off-screen
• Can create illusions with a holographic projector
• Died in the battle with Unicron
