From Season 2.5 of the Generation One timeline, a tale that brings back Powerglide and his unlikely girlfriend, Astoria Carlton-Ritz: Breaking In.
As the Combaticons take over a Hybrid Technologies facility, Astoria comes back to take control of her company: there are things in that facility that belonged to her beloved father--and she wants them back! Optimus Prime, Prowl, Bulkhead and Deep Cover mount a counterattack, but Onslaught and Blast-Off took some hostages. Who's gonna solve the stalemate?
The Lost Seasons presents one of its largest updates ever: a 14 pages comic (plus cover and intro page) which is also an actual lost episode from the Generation One portion of the Lost Seasons continuity!
