My first thought was Unicron--transforming monster planet who can also reformat me as a vastly more powerful version of myself--but then i wondered if he counts as a Transformer. Even if he does, though, can i trust him to fight on my behalf? He might not care if i'm in danger, and regardless of the outcome of my fight, he might eat my planet while he's in the neighborhood, including eating my friends and maybe even me, despite my high fat content.
So then i thought of Primus, but as with Unicron, does he count as a Transformer?
Then i thought of Optimus Prime--even if he gets killed, he'll just come back to life somehow, quite possibly in an even more powerful body.
Then i thought, The Last Autobot would be an even better choice. Even if
i die, he'll bring
me back to life, quite possibly in an even more powerful body. Heck, he quite possibly might re-create me in an even more powerful body even if i
don't die. Unicron-style upgrades, less planetary peril.
Then i thought, wait a minute--this is the Toy Talk forum. So obviously the question is what Transformers TOY would you want at your side in a fight.
In that case, probably G1 or Masterpiece Megatron. If i'm fighting a Human, maybe i can bluff that i've got a real gun; if i'm fighting a Transformer, maybe i can bluff that i've got
Megatron to do my bidding.
i've also read that Japanese G1 toys, being subject to different safety laws than US releases, came with spring-loaded weapons capable of launching with enough power to actually do some damage. So i guess that tips things in favor of Japanese G1 Megatron rather than Masterpiece Megatron--i don't think the Masterpiece actually fires projectiles.
Then again, maybe i should choose a toy with pointier projectiles? Or maybe a toy with its own pointy parts or sharp edges, for use as a melee weapon. Or maybe i should pick the heaviest toy to use as a bludgeon (which, ironically, rules out Bludgeon).
In "conclusion", what Transformer would i most want at my side in a fight? That depends on a number of things.
Am i a Transformer myself, or a Human, or what?
As Roadbuster said, who am i fighting?*
Are Primus and Unicron Transformers? What about Transformers Crossovers, such as Death Star/Darth Vader?
Can i safely trust that any TF i choose will fight for me, and neither betray me, nor ignore my plight?
*idea to make this thread more interesting: Imagine that whoever posted before you is Human, and allied with the TF they chose, and THAT's who you're fighting (so you must choose somebody different than the poster before you chose). Since my post is such a "multi-answer", and Roadbuster's is such a "non-answer", the next person should choose one Transformer (or one Transformers toy) to bring along to fight Roar (Human) and Ravage.
