He is mentioned so yes but he has not made an on screen appearance. I hope we see him in the future.

It would be interesting considering that TLT is a multiversal entity, that would mean that the TLT we might see in the films is the same one we see in the comics.

Yeah, I feel that might be the same with Uatu the Watcher. I'm pretty sure the Watchers are multiversal being as well, so would that mean that Uatu from the What If... show is the same Uatu from the comics? I might be wrong. Also, TLT was supposed to show up kn Infinity War but was cut.

When did mordo mention him?
