Zaxxon is a classic 1980s game that has gotten very little nostalgia. It captures the feels of the pop sci-fi feel of 1982 in between Empire Strikes Back and Return of the Jedi.
Nothing so cute at first, but at later levels cute Zaxxon dragons appeared, but few had enough skill or quarters to reach that level.
Of vexillological note are the red pennant markers that denoted ones level.
The Zaxxon of Temple had a diamond coat of arms of green, yellow, and white. The field is green and what looks like bolts of yellow lightning under a white Z are visible. Note the Z is crossed with a mid mark.
It seems in Zaxxon lore that dragon like lizard beings created these floating space fortresses. In the game, if a pilot is skilled enough the red, blue, and green dragons make an appearance to defend their space fortresses.
Maybe a reboot of Return of the Zaxxon Dragons - 2022 is overdue?
