Angel O7 has a similar design to Tualatin.
This card has the same effect as Majesty's Fiend.
Like this card is Level 7, there is also a Level 1 Angel O1.
The O in Angel O7 is the letter O (Oh) and not the number 0 (Zero), so the correct pronunciation of its name is Angel O Seven, not Angel Seven or Angel Zero Seven. This is more evident from its Japanese name.
The card's name could also be a play on the name Angelo", meaning angel or messenger.
