Spanish Transformers Comics

In Spain, going by some issues I found in a comic shop in Barcelona back in 1999, Marvel US's stories were reprinted (and translated) in bumper 64-page bimonthly issues.

Each issue contained two Transformers stories and one "backup strip", in this case, ROM.

On the odd occasion, translated Universe entries were translated as well. In issue 65, Shockwave and Unicron were featured. Also in issue 65, there was a one-page comic strip featuring Jazz on an important mission...

The contents of the issues I found were as follows, and just for fun, see if you can figure out what the original English titles were:

Issue 61 - "Todo Se Hunde!" and "¡Ritmos de Oscuridad!"
Issue 64 - "2a Guerra Civil" and "¡El Tiempo se Acaba!"
Issue 65 - "El Vacío" and "¡... Al Borde de la Extinción!"
Issue 66 - "¡Aún Vive!" and "¡Éxodo!"
Issue 67 - "Un Círculo Salvaje" and "El Último Autobot"
