"Okay, everyone, let me explain to you about the type of Digimon. Digimon has three types of attributes. First is a vaccine attribute, they are created to prevent the destruction of important Data by Virus Digimon. They have a strong attack instinct against Virus Species, so they act to combat the Virus Species and thus protect the surrounding environment and its territory. As a rule, Vaccine Digimon is usually good, but they have a high emphasis on justice and morals, and the fight against evil.
The second is a data attribute, they are like the e-mails that are sent using computers. They do not belong to either "Vaccines" or "Viruses", but they need "Vaccines" to protect themselves from "Viruses". They just exist according to the already established environment and don't do much to change it. Data Digimon can be good or evil, but generally value peace above all.
The third is a virus attribute, they are Digimon that devours data, recognized as evil Digimon that destroys data from computers. Virus species seek to modify the surrounding environment according to their wishes. As a result, anomalies end up appearing in the system. Virus Digimon desires power, and can often become greedy, selfish, wild, or evil in pursuit of it.
Well, even though there is always an exception, especially for virus attribute Digimon that more good if they have a trainer that they want to protect.
You can read the Digimon encyclopedia to know every type of Digimon so as not to misunderstand every Digimon you see.
Besides that corresponding to these three attributes, we can make a conclusion Vaccine strong against the Virus, Data strong against Vaccine, and Virus strong against Data.
Of course, there is another exception. The elements of Digimon are fire, wind, ice, poison, plant, earth, thunder, holy, demon, metal, etc.
As you know in nature fire is weak against water, and water is weak against the earth, same for the other element, but holy and demon elements are special.
Holy is strong against Demon but demon weak against holy. The demon is only strong against other normal elements like fire, water, earth, thunder, etc. Even though the holy type is not strong against other normal elements but it is not weak either.
That's also why holy and demon Digimon is been searching for and cherished. Especially these two special Digimon is as rare as diamond.
That's why holy and demon elements Digimon trainers must be prepared and responsible for he/she is Digimon. Because they are most likely to be targeted by someone else.", said Teacher Fran while looking in my direction.
Suddenly Mike raises his hand, " Teacher, I want to ask why child-level holy Digimon Digimon more easily evolve to normal elements Digimon than level higher?"
"Oh, it is because the holy power inside child-level Digimon is unstable and abundant so when it evolves, there is a high chance for this Digimon to evolve to normal Digimon. Different from the adult level or higher because we can give holy type core or food to make it is holy power in balance as this Digimon will not evolve to normal elements Digimon. As for the core, you can get it from the adult level or higher Digimon body."
"I see. Thank you teacher", said Mike.
"Okay, is there another question?", said Teacher Fran.
"Me, Teacher Fran.", Michael said while raising his hand.
" Yes, what is it, Michael?", said
"Like this, a teacher I want to ask about Jovan's Plotmon. is she okay because her behaviour is you know ?.", said Michael.
"I know what you mean, that's why I said there is always an exception including Jovan's Plotmon. From what I can see that Plotmon is more suitable to become virus attribute Digimon when it evolved. Especially she is very protective of Jovan that unusual holy attribute Digimon do. So we can see Plotmon is very dependent and close to Jovan.", said Teacher Fran.
" Oh, I see. Thank you, teacher.", said Michael and sit back in his seat while thinking.
"Alright, are there any other questions? ... No? Okay, then we are going to dismiss this class. See you tomorrow.", said Teacher Fran and left the room.
"Yes, thank you, Teacher Fran.", then we are also starting to pack up and go back home.
