Bumblearm

Bumblearm is an Autobot combiner from the Robots in Disguise portion of the Aligned continuity family.

"You mean we turned into that blimp because I bent one lousy finger?!"

Bumblearm is the combination of the Bumblebee and Strongarm, made possible through a combination of DNA-altering radiation and mad Mini-Con science.

Fiction

2015 Robots in Disguise cartoon

While attempting to arrest the Stunticon Heatseeker, the Bee Team were exposed to Heatseeker's combining ability, nuclear radiation from a nearby disposal site, and an explosion, King of the Hill (Part 2) giving them the ability to combine into Ultra Bee. The Great Divide Fixit began research into controllably duplicating the combination ability, which finally resulted in a mostly successful test, fusing Bumblebee and Strongarm into Bumblearm. The test was only partially successful as Strongarm, forming the lower half of the combined bot, was unable to move, leaving Bumblearm stuck in place until the combination effect wore off. The Fastest Bot Alive!

Toys

While Bumblearm does not have any toys to their name, an "unofficial" configuration can be made by mix-matching the Crash Combiner figures of Bumblebee and Strongarm, as they can respectively take on the upper and lower half of a combined figure. However, the resulting gestalt resembles a larger, bulkier form akin to Dragbreak, rather than the mix-matched character model used for the show.
