7 Most Important Things We Still Haven't Seen In The X-Men Movies

6. Bastion

Bastion started out life as two separate beings, the advanced sentinel Nimrod and the sentinel Master Mold, the giant robot charged with creating an endless supply of the mutant hunting machines. When Nimrod, disguised as a human, stumbles across a piece of the inactive Master Mold its brain is taken over, with Master Mold sculpting Nimrod into a new image and forming Bastion. There's a bit of wobbly comic book sci-fi involved too but it's best not to go too deeply into that. The resulting being is known as Bastion, and although he initially wakes without his memories it's not long until he gets back on his mutant hunting horse. Being the evolution of the Master Mold, Bastion can control all other sentinels at will, whilst also transforming people into so called Prime Sentinels. We haven't seen the Master Mold for fairly obvious reasons (a giant, robot construction site in humanoid shape might be a bit hard to swallow in Singer's X-Men universe) but we have seen the Sentinels. The shape shifting Sentinels of DOFP also share more than enough similarities with Nimrod, so having one of them cross the timeline into the new continuity, become more powerful and disguise itself as a zealously anti-mutant human could be a way to introduce a genuinely terrifying, Terminator-like threat such as Bastion. Bastion ended up in Government in the comics so we could even see him working alongside the new timeline's William Stryker by day and murdering mutants by night.
