We know the All-Spark can create new life, but it only seems to animate electronics or machines with atleast rudimentary electronics running through them. We also know that any new cybertronian life is highly agressive, as seen when Sam was attacked in his home by his recently animated appliances. If you think about it, it would make for a devastating smart bomb. If the rival world poses a threat to you technologically, their own technology will come to life and strangle them, but if they are sticks and stones primitive, you can own them easily. So was the All-Spark made with nefarious purposes in mind.
The Allspark wasn't made with any purpose in mind. It's just sort of something that came into existence.
Technically, anything can be a weapon. But no, the Allspark does not seem to have been designed with military purposes in mind.
I don't think it was made with the intention of being a weapon, but it was possible to use it as such.
But the way the All-Spark works is just too specific. If it lands on some lifeless rock, it won't have the technology it needs to create new life. If it does land on a world with the tech it needs, the new lifeforms are murderous and will spring up and kill the natives. This thing has weapon written all over it.
It was Chuck Norris' Rubix Cube and since he can use anything in the room as a weapon - including the room itself - yes, it is a weapon.
Rock Lords: The Movie! Is the Allspark even technology-based? It looks like it's been carved and it breaks into rocky shards when destroyed. It's the radiation it emits that gives life so maybe after a while it'll give up on trying to affect technology that isn't there and effect something else instead. We just assume it only affects technology because that's all we've ever seen it do. It's comfy doing that but I'm sure it could eventually adapt.
The transformers it makes are feral, like threatened animals in a weird habitat. They're not evil asides from the occasional evil laugh Michael Bay makes them do. Optimus was like that once >:O
I still like the idea of it being a weapon to wipe out a tyrannical empire that had it's seat on Cybertron (Quintessons?) by turning their own advanced technology against them. Then as the planet was left alone for millenia, the feral machines didn't destroy each other as planned, but evolved and ended up sentient. But that's a fanon thing. I don't think we ever found out what it actually was.
I don't think it's evil. It just depends on who has it in their possession. Optimus wanted the Allspark to rebuild Cybertron, Megatron wanted it to make an army to take control of the Earth/Galaxy/Universe/Whatever.
Actually, there's no reason to believe it wouldn't. It's known that the Allspark brought "life" to Cybertron, where presumably there wouldn't have been electronic devices beforehand (not even naturally occurring pulleys and gears). It could very well be that the Allspark could animated lifeless rock into something cybertronian-esque, but that the process would take far longer than simply animating something already close to a cybertronian life-form in composition.
I 'don't think the cube is anymore evil than a steak knife, or the protoforms any more evil than lions or snakes. It's the intent behind making them that I'm questioning.
