Ikaruga Mk.II

An improved version of Tenba's Ikaruga Mk.I, this monstruous machine has nigh impenetrable physical defenses and almost perfect elemental resistances, making quite hard to damage it except with non-elemental or Wind-elemental magic attacks. Additionally, it has quite large variety of skills: its 100M Vulcan deals large physical damage to a single target; Simultaneous Swipe causes large physical and Thunder-elemental damage to all vanguards; Death Gear deals average physical damage to a single target; Alarm allows it to summon Asukas as backup; can use System Uncontrolled in order to change into a more aggressive attack mode whenever it gets hit with a Wind-elemental attack; and finally, it has a Lv. 3 Stored Attack, Photon Spreader, which causes large amounts of Thunder-elemental damage, and it'll initiate a countdown for using it immediately after using Alarm.

However, it also uses Safe Mode after an attack in System Uncontrolled mode to change to a less aggressive mode, in which all of its defensive stats lower severely, allowing you an opening to attack. However, since this means that a group of three Asuka will most likely be there due to it using Alarm during System Uncontrolled, it means that you will have to use party-wide attacks such as the Super Counters of your party or strong Song Magic in order to be able to attack it.
