Question about Sun Dragon

By High Elves 77, in Warhammer: Diskwars

Can the Sun Dragon target himself with his focus ability or must he target another disk within medium range?

The Sun Dragon can target himself, as the ability wording states "target disk." If it said another disk, then it would exclude him as a target.

The ability to hit himself is what allows him to pin a mass of enemies and incinerate them all. He can, of course, choose to target other friendly disks or enemy disks.
