Difference between MK2 and MK1

the difference of The Disaster and Disaster MK2 excluding their strength is
The Disaster:
1.is the result of Falcon's Overflow fusing The Destiny and Star Caster.
2.the armor conciousness,Beast is the manifestation of Falcon's grudge against the accelerated world and the ARS.in 7000 years of living in the accelerated world and gaining massive knowledge and experience Beast has evolved from Negative IS into a Being.
3.if the Burst Linker infected by the Armor lost his BB,the Armor will infect the Burst Linker that defeated Chrome Disaster.
4.if a Burst Linker has enough compatibillity with the Armor,he or she can use the skills of the previous Disasters and if the compabillity is high enough the Burst Linker may gain access to Beast's Skill <Attack Prediction>,the only one who has access to all of the previous Disasters and Beast's Skill is the former 6th generation Chrome Disaster.2nd to 5th generations can use skills of the previous Disasters albeit not all of the skills.
5.once a Burst Linker is infected with the Armor,Beast will whisper to the infected to equip the Armor to turn he or she into Chrome Disaster.
6.if one does not have compatibillity with the Armor,they will turn into a berserker seeking to kill all Burst Linkers(failed fusion),if one has high compatibillity they will fuse with Beast completely and become a 'complete" Chrome Disaster(complete and successful fusion)
Disaster MK2:
1.is the result of the ISS Kit Core's accumulated Negative IS that it collected from the ISS Kits transferred to Cerberus III when he equipped 4/5 of Invincible.
2.instead of possessing or fusing with Cerberus,it instead turned them into its core.
3.instead of being more like a Burst Linker,MK2 is more of an artificial Being.
4.does not have sentience like an unevolved Being.
5.unlike the original,MK2 does not have access to Cerberus I,II and III's skills.MK2 only has Dark Shot,Dark Blow and Invincible's Dreadnought mode.
6.does not infect upon defeat unlike the original?
7.only 40% of the expected result according to Vise.

Original Disaster:Burst Linker/Pseudo Being.
Disaster MK2:Being.
in terms of which is stronger:Original>MK2
