Electro-sword
From MediaWiki

Like the rest of his sword-wielding Predacon teammates, Tantrum also carries a sword. In his case, it's an electro-sword, which is perpetually sheathed in a web of powerful electric bolts that can disable his prey in addition to being sharp and pointy. Owie.
Insecticon overkill extraordinaire Barrage also packs an electro-sword of his own. He mostly just uses it to hack your body into itty-bitty pieces after he’s shot you in the face five times.
