Well, the whole "shortening travel time" is unlikely to be a thing. Chaining together Teleportation or using Super Speed for extended periods of time is going to exhaust your character VERY quickly - you would maybe cover 1-2 kilometers (10-20 teleportations of 100m each) in, let's say 20-40 seconds (2 seconds of chargeup per teleport) before collapsing from the exhaustion. Super Speed is not going to be quite as exhausting I believe, but unless you have ridiculous SPD stats any vehicle will outmatch your character. You'd best stick to regular travel with vehicles for high-distance travel. They're about as fast as teleporting like I just wrote, and won't exhaust you one bit.

Opening portals would have to be divided into various moves of their own. The portal that would suck up a projectile and send it out another way would be one thing. Same for say, opening a portal beneath someone's feet and one in the air to drop them from it and injure them through the fall. This is the only difficult thing on this list - I'd recommend that you make a list of the applications you want it to have.

And finally, Repliku using it to instantly travel around the battlefield would be a pretty straight application of teleportation. You could fashion it into a move if you want it to open a portal that stays open for a few seconds - again, refer to Blink's roster for that one - or just have Repliku vanish in one place and reappear in another.
