Kairus's Links
Kairus is actively hunting down Gyder to convince them to stop using them as a disguise. While they aren't happy to have a negative reputation due to Gyder's actions, it does come in handy sometimes.
Gyder has been known (well, not really) to steal Kairus's form to go undercover for more violent missions. This is due to Kairus's reputation in the Germ Underground as being someone you wouldn't want to mess with. This reputation is actually Gyder's fault in the first place.
