I think there's a lot of difference between linear movement to and beyond light-speed - which (pretty much every starship in SF can do) and having near-light superspeed with manouvering faculties, which is a distinct and useful super-power.

I recall having this conversation with Scott back in the day regarding Amazing Guy's ability to quantum-jump across galaxies. We eventually figured that there were conditions preventing this happen in strong gravitational fields like those found on planets, so he could only use that ability when he was in deep space. It was a way of preventing him from being able to hop in and out of fights too easily and thus wrecking any drama or threat.

Now that G-Eyed's back in play with his teleportation powers I'm going to have to be very careful too. Since that's G-Eyed's primary shtick (clever use of his abilities also enhance his strength and stamina to around Spider-Man levels but I don't want to explain how we link that to teleportation right here) it means I need to demonstrate why he's the go-to guy for teleportation - and not Liu Xi or Al B. or Xander or the Shoggoth or any of the other people who have been shown to accomplish similar effects; and I have to do it without downgrading or taking anything away from other cast.
