Asterians
The Asterians are your resident ancient elitist alien race in Warpath. They're kind of like Eldar in Warhammer 40,000 and have similar units, although their fluff doesn't really cross over. They started as an army in Deadzone, but have now made the jump to Warpath in the new alpha rules.
Background
The Asterians are the oldest race in the setting, having traveled through space when all the other races were still playing with themselves on their homeworlds. Interestingly enough, every other sentient race has stories of Asterians kidnapping members of their species throughout their histories, seemingly making them the setting's grey aliens even though they don't look like them either. Regardless, most races don't trust them because of these past encounters.
Dreadball
The Asterians have two teams in Dreadball split between two seasons. The Shan-Meeg Starhawks were introduced in Season 3. They get access to all four player types, and their base team kit even comes with a defensive coach. Their team rules are split between their player types and include some once per game effects, so bookkeeping is required. Their guards have an ability that allows them to claim they were fouled on the pitch, forcing a check against an opponent's player. This can only be done once per game per player though.
Their jacks and strikers both have a rule called "Fragile" that gives them a single automatic fail on any armor check. This really sucks, but is supposed to be balanced by the second jack ability which lets them claim they were fouled as they pass by an opposing player. This forces a check just like with the guards mentioned above. So basically they're dirty, cheating space elves.
The Bremlin Nebulas were introduced in Season 5 and are female space pirate Asterians. They only have access to strikers and jacks, which is somewhat limiting. In the fluff they're said to be the most common type of Asterian most Humans encounter, leading to a "distorted" view of Asterian culture, at least according to the Asterians.
